Function Parameter Setting
Restore the adjustable frequency drive H-03 [2] Restore - make a power cycling - press reset
1) Set motor parameters:
Set the motor parameters according to nameplate
data
P-02 to P-07
F-04 & F-05
As stated on motor nameplate
Perform a full auto tune P-04 [1] Enable complete auto tune
2) Check that motor is running in the right direction.
When motor is connected to an adjustable frequency drive with straight forward phase order as U - U; V- V; W - W motor shaft usually
turns clockwise seen into shaft end.
Press [“Hand”]. Check shaft direction by applying a
manual reference.
If motor turns opposite of required direction:
1. Change motor direction in H-08 Reverse Lock
2. Turn off line power - wait for DC link to
discharge - switch two of the motor phases
H-08 Select correct motor shaft direction.
Set configuration mode. H-40 [3] Process
Set Local Mode Configuration H-45 [0] Speed Open-loop
3) Set reference configuration, i.e. the range for reference handling. Set scaling of analog input in parameter AN-##
Set reference/feedback units
Set min. reference (50° F [10
°
C])
Set max. reference (176° F [80
°
C])
If set value is determined from a preset value
(array parameter), set other reference sources to
No Function.

Set S201 or S202 to desired analog input function (Voltage (V) or milli-Amps (I))
NOTE! Switches are sensitive - Make a power cycling keeping default setting of V
5) Scale analog inputs used for reference and feedback
Set terminal 53 low voltage
Set terminal 53 high voltage
Set terminal 54 low feedback value
Set terminal 54 high feedback value
